- Poseidon Outer Reef Cruises - Cruising from Port Douglas aboard the modern high speed dive and snorkel catamaran Poseidon, you’ll have more time to spend at three fabulous snorkeling and diving sites on Agincourt Reef’s outer limits. Renowned for its coral and marine life, the reef is known for being the best diving and snorkeling day trip destination from Port Douglas.
This cruise suits experienced divers and beginners alike, whether you’re a certified diver or you just want to go snorkeling. If you’re a diver, you can take up to three dives into the Great Barrier Reef’s coral gardens. You have your choice of diving from the mooring site, doing a drift drive back to the vessel or taking an excursion to less easily accessed sites depending on the conditions of the day.
- Great Barrier Reef - If you’d prefer to stay on top of the water, go snorkeling in sheltered lagoons with breathtaking drop-offs. Learn about the Great Barrier Reef’s fragile ecosystem during a reef interpretation talk, and then take a guided snorkel tour for an informed look at the reef’s tropical fish and coral.
Poseidon has been specially designed to enhance your snorkeling and diving adventure with a lowering transom for easier access to the water, an air-conditioned saloon and open deck areas for relaxing on the reef. You’ll also have plenty of chances to hydrate and re-fuel with an included morning tea, afternoon tea and buffet lunch with prawns.
